ABSTRACT:
Motion of the moving handrail of an escalator or moving walkway is interrupted in the event that a foreign object is carried into the handrail reentry housing area on the handrail. Handrail movement stops independently of movement of the conveyor steps, so that the handrail will stop even as the steps are still decelerating as a result of an appropriate signal from a reentry housing foreign object sensor. The handrail will be reset for further motion after the steps stop but will not commence further movement until the steps are intentionally restarted.
